摘　　要：基于山西某矿11207工作面巷道变形特征及围岩受力特点,提出使用锚索对顶板、巷帮进行补强支护,使用工字钢+单体组成的抬棚进行二次加固,之后通过化学注浆方式加固,提升巷道围岩自身承载能力、稳定性。经现场应用后,11207运输巷围岩变形量控制在150 mm以内,可满足巷道后续使用需要。Based on the deformation characteristics of the roadway of 11207 working face and the force characteristics of the surrounding rock in a mine in Shanxi,it is proposed to use anchor cable to reinforce the top plate and the roadway gang,and use the lifting shed composed of I-beam+monolith for secondary reinforcement,followed by reinforcement by chemical grouting to improve the bearing capacity and stability of the surrounding rock of the roadway itself.After field application,the deformation of 11207 haulage lane is controlled within 150 mm,which can meet the needs of subsequent use of the lane.
